Announce multiple transactions at the same time

[ianninirojas]

two or more transactions are announced at the same time. In such a way that if a problem occurs in the communication, it is guaranteed that all were announced or not all were announced.

Something like Aggregate Transaction of the new version of catapult, but that all transactions are independent in the blockchain.

I have to announce N transactions, but if I announce them one by one, it may happen that when the N-3 transaction is announced, a problem occurs on the server where it is running. Then I would like to know if there is a way to know if they are all announced at the same time or not.
